To all whom, it may concern Be it known that I JOSEPH F. Corina, acitizen of vthe United I city of Chicago, countyof Cook, and-Statestates, residing in the ing and guiding the sliding doors of'freightcars, and the invention Consists in the fea-- tures of noveltyhereinafter described, illustrated in the accompanying drawing "andparticularly pointed out in the claims at the end of this specification.

Figure 1 is a view in side elevationshowing part of a freight car bodyequipped with a sliding door provided with my mproved door-supportingand guide mechanism. Fig.

' A designates the side wall car and. B denotes the slidin. doorthereof. Above the top of the door and fastened to the overhanging part"of the car wall is an upper guide plate C that serves to prevent theoutward movement of the upper part of the car door B. To the lower edgeof the car doorB is secured a Z-shaped bar I) that extends from front torear of'the door. This Z-bar D has ansupper member extending verticallyalong the lower portionof the door B and has a horizontal memberextending beneath the edge of the door and an inner vertical memberextending downwardly and inside the track bar "E; In the present form ofmy invention, this track bar E consists of anangular guide. This trackbar E is supported by brackets F which are arranged at convenientdistances apart beneath and along the path of travel of the door B. Eachof the brackets I5 is preferably formed as a metal casting having itsbody strengthened by upwardly projecting-ribs fand having an-inwardlyprojecting or thickened portion or boss 7" extend ing toward and adaptedto bear against the Specification oflietters Patent. ra ncanon'fiiea Mays, rare.

casting,' a channel adapted to receive the ower member of the trackbar'E. Each of the castings is secured to the car body by means ofthrough bolts 10 and 11, the 10 passing also through the lower verticalmemberofthe track bar E and -servingtosecurely hold said track bar inplace.

Itwill be observed that the shape of the casting F is such that thetrack bar E-may he held at suiiicient distance from the wall ofthe carbodybencath' thefloor G to en- 'to move freely back and seen, also. thatthe horiprojects through the door the lower portion of the door-openingis access of dust, cin than if the floor G termiwith the vertical memberof One of the brackets F located nated in line the Z-bar D. e ie e hopening is formed with an upward extension F having a (cam-shaped innerface f adapted to contact with the depending in of the Z-bair D, so thatas the is moved to closed position, the cam the upward extension I" willforce door face of the door inward and thereby cause it to more tightlyclose the door-opening of the car. Inasmuch as this upward extension; Fof the'bracket-bears against'the vertical member of the track bar E, theoutward strain upon such vertical extension is resisted by the track barand the danger of breakage of the bracket is materially lessened.

I do not wish to be understood as claiming in the present applicationthe construction of the bracket F, as this forms the subject-matter ofaseparate application filed by me ofeven date herewith.

To the lower portion of the door B are secured a series of rollersupporting bracket s, the preferred construction of which will next bedescribed. Eachof these brackets is shown as consisting of a chamberedcasting or casing II, the outer face of which is strengthenedby ribs .itand each casting is connected to the door by means of through the Z-barD extends some .distance inward beyond the outer edge of the floor Gthat .opening' of the car, as by this construction left-hand side of thedoor- Mid iii]

bolts 12. The chambered portionlof each of the castings H: whichprojects inward from the upper face of the casting, sets within acutaway space or recess formed in the lower edge portion of the door Band in the Z-bar D. Within the chambered portion of each of the castingsH ismounted a roller K adapted to travel upon the surface of the trackbar E. Each'roller K is mounted upon a pintle 15 that projects outwardlythrough the chambered portion of the casting and through the front wallor diaphragm k that is formed as an integral part'of the casting H. Thatportion of the pintle 15 that projects through the wall 72. 1spreferably reduced, as at 16, and through the outer reduced end portionof the pintle is passed acotter pin 17 that serves to securely. hold thepintle in place.

I nasmuch as the chambered portion of each of the castings H extendsbeneath the door and is approximately equal to the thickness of thedoor, the casting takes up but very little room and affords a veryfirmand secure housing .for. the roller K. It. will be understood, ofcourse, that the pintles 15 that support the rollers K'will be insertedthrou h holes in the inner walls of the castings and the shoulderedouter portion of the pintles will prevent their being withdrawn from thefront, even if the cotter pins should be removed. Y a I The slidingdoors of freight cars being subjected to extremely severe strains inuse, it is highl important that the door-supporting rol ers should besecured in the most efi'ective and stable manner, and inasmuch as thecastings H are carried within seats or cutaway spaces in the lower edgeof the door and in the Z-bar 'D, they will be so firmly held as to guardagainst danger of;; displacement under the severe strains of service.

'It is obvious that .the precise details of construction above set outmaybe varied -vwithout departingfrom the spirit of the in-' vention andthat features of the invention may be employed without its adoption asan entirety. 7 Having thus described my invention, what I claim asnewand desireto secure by Letters Patent is+ 1. In mechanism of thecharacter described, the combination with a sliding door and with atrack supported beneath" said door, of a Z-bar attached to the loweredge ofthe car door, both said 'Z-bar and said car door having recessesformed therein, a

plurality of casings arranged within said recesses of. the car door andZ-bar, and a plurality of rollers within said casings and adapted totravel upon said track.
